Rapid infrastructure scaling with record cluster deployment and compute growth; limited direct frontier capability or policy data. Model synthesis · opinion

Climbing Confidence 26%
No energy figure found. No verified energy-consumption figure was found in the sources we read (all of them were readable), so this entity is ranked on the remaining 70% of the weight (67% of it scored) with confidence reduced. How coverage works.

Δ = change vs run N-1 (2026-10-08). Index = weighted mean of the scored categories (weights renormalized over what was scored) · coverage 47% · confidence 26% · measured share 43% of the scored weight (opinion 57%). No “overall” is asked of the model. Scores are AI-assisted (disclosures).

Run history

Every published measurement, newest first. N is the run on the leaderboard now; failed attempts are not shown. Unranked runs show no Index; Δ and the Index trend compare ranked runs only.

A later run (2026-10-09) completed but found too little verified data — insufficient data: energy undisclosed and 39% of the remaining weight scored (needs 60%, including compute or growth) — so it was not published. Run N stays current.

Measured — computed in code from reported figures

Joules · weight 30%

Energy throughput

—no data

No verified annual energy-consumption figure was found, so this category is unscored.

P = annual energy (J) / seconds per year → average watts. Score = clamp(2.5 × (log₁₀P − 7), 0, 10). Kardashev-equivalent K = (log₁₀P − 6) / 10.

Watts of thought · weight 20%

Compute capacity

7.9/ 10

Reported operating data-center capacity: 1.4 GW (June 2026) = 1,400 MW → score 7.9.

Planned / under construction: 2,000 MW (YE 2026) — shown, not scored.

Score = clamp(2.5 × log₁₀(MW), 0, 10). · confidence 65%

Slope · weight 15%

Growth gradient

—no data

Fewer than two comparable annual figures were found, so growth is unscored.

Each available sub-metric's compound annual growth rate (up to 3 years) is mapped piecewise-linearly through the anchors, then combined with weights capex 50%, revenue 25%, energy 25% (renormalized over what is available).

Opinion — model-judged against written rubrics, from verified quotes only

Opinion · Policy · weight 8%

Permission to build

—insufficient

No evidence on permitting, energy or regulatory positions.
